The sleeve 6 is inserted into the grooves 3 and 3a formed along the longitudinal direction, and the sleeve 6 is installed to be rotated relative to the inner tube 4, and the base of the case 7 is sleeved. Located below the base of 6, an annular space and a smooth cylindrical bearing portion are formed between the inner tube 4 and the case 7, while the annular space has an inner tube (as shown in FIG. 2). 4) is elastically deformed while bending radially outward from the base of the collar 10 coupled to the base of The tip portion 19 of the projection 9 is inserted into friction with the inner wall of the annular space.

여기서, 상기 칼라(10)의 베이스부에는 길이방향을 따라 홈(11,11a)이 형성되어 있고, 이 홈(11,11a)에는 내부관(4)상에서 칼라(10)가 상대 회전되지 않도록 내부관(4)의 베이스부상에 형성된 리브(12,12a)가 끼워지며, 또한 내부관(4)의 일단에는 환형외륜(13)이 형성되어, 이 외륜(13)을 매개로 상기 칼라(10)가 축방향으로 지지되고, 타단에는 다른 환형외륜(14)이 형성되어 있는바, 이 외륜(14)의 일부는 상기 홈(3)에 의해 갈라져 있는 한편, 슬리이브(6)를 고정시키도록 슬리이브(6)의 대응단과 탄성결합됨과 더불어 돌기부(9)의 선단(19)와 반대방향으로 상호작용하게 되어 있다.Here, the grooves 11 and 11a are formed in the base portion of the collar 10 along the longitudinal direction, and the grooves 11 and 11a are provided so that the collar 10 does not rotate relatively on the inner tube 4. Ribs 12 and 12a formed on the base portion of the tube 4 are fitted, and an annular outer ring 13 is formed at one end of the inner tube 4, and the collar 10 is formed via the outer ring 13. Is supported in the axial direction, and another annular outer ring 14 is formed at the other end, and a part of the outer ring 14 is divided by the groove 3, while the sleeve is fixed to fix the sleeve 6 In addition to being elastically coupled with the corresponding end of the eve (6) it is to interact in the opposite direction to the tip (19) of the projection (9).

따라서, 상기 내부관(4)이 슬리이브(6)에 대해 상대회전되면, 상기 이동컵(1)은 홈(3,3a)내에서 축방향으로 배치되게 되고, 상기 칼라(10)는 내부관(4)에 의해 회전됨과 더불어 이 칼라(10)의 돌기부(9)의 선단부(19)는 외부관케이스(7)의 베이스내면과 탄력적으로 마찰접촉되게 되어, 부드럽고 정규적인 마찰이 일어나게 되는 한편, 이 마찰을 상대적으로 감소시키고자 할 경우에는 칼라(10)의 돌기부(9)일부가 베이스부에 대해 균등하게 분포되도록 제거되게 된다.Therefore, when the inner tube 4 is rotated relative to the sleeve 6, the moving cup 1 is arranged in the axial direction in the grooves 3, 3a, and the collar 10 is the inner tube. In addition to being rotated by (4), the tip portion 19 of the protrusion 9 of the collar 10 is in elastic friction contact with the inner surface of the base of the outer tube case 7, so that smooth and regular friction occurs. In order to reduce the friction relatively, a part of the protrusion 9 of the collar 10 is removed to be evenly distributed with respect to the base part.

그리고, 상기 내부관(4)과 슬리이브(6)는 폴리스틸렌이나 폴리프로필렌, 상기 칼라(10)는 아세텔수지, 상기 케이스(7)는 폴리스틸렌과 같은 재질로 성형되는 바, 이와 같은 재질대신 기공지도니 적당한 플라스틱재질도 사용될 수 있는 한편, 이 플라스틱의 마찰이 탄성저항을 감소시키기 위해 실리콘이나 유리섬유, 몰리브덴 또는 포리테트라 프로로에틸렌(polytetrafluoroethylene)과 같은 혼합물로 합성시킬 수 있으며, 상기 케이스(7)는 경합금이나 구리합금과 같은 금속으로 형성될 수 있다.The inner tube 4 and the sleeve 6 are made of polystyrene or polypropylene, the collar 10 is made of acetel resin, and the case 7 is made of a material such as polystyrene. Known plastic materials may also be used, while the friction of these plastics may be synthesized in a mixture such as silicone or glass fiber, molybdenum or polytetrafluoroethylene to reduce the elastic resistance, ) May be formed of a metal such as a light alloy or a copper alloy.

한편, 제3도 내지 제9도에 도시된 본 발명 2 실시예로서 적용되는 립스틱케이스에는 제1도 및 제2도에 도시된 1실시예로서 적용된 립스틱케이스와 같이 내부관(4a)과 슬리이브(6a), 케이스(7a) 및 칼라(10a)가 구비되어 있는 한편, 1실시예의 이동컵(1)과 유사한 스틱운반용 이동컵은도면을 간략화시키기 위해 생략되어 있다.Meanwhile, the lipstick case applied as the second embodiment of the present invention shown in FIGS. 3 to 9 has the inner tube 4a and the sleeve as the lipstick case applied as the first embodiment shown in FIGS. 1 and 2. 6a, case 7a and collar 10a are provided, while the transfer cup for stick transportation similar to the transfer cup 1 of one embodiment is omitted to simplify the drawing.

여기서, 상기 내부관(4a)의 베이스부에는 2개의 환형외륜(15,15a)이 형성되어 있는바, 이 외륜(15,15a)은 그 단면이 삼각형으로써 내부관(4)이 베이스부의 선단부로 부터 윗방향으로 경사지게 형성됨과 더불어 환형베어링부(16)와 축방향으로 지지된 순차적으로 형성되어 있으며, 환형리브(17)는 상기 내부관(4a)의 맞은편 외륜과 상호작용되어 내부관(4a)상에 축방향으로 지지된 슬리이브(6a)가 자유회전될 수 있게 되고, 재부관(4a)의 베이스부의 상기 리브(15,15a)는 내부관 (4a)상의 칼라 (10a)를 제8도 및 제9도(제4도에서는 실선과 파선으로 도시됨)에 도시된 2개의 위치로 고정시키도록 칼라(10a)의 베이스부에 형성된 내부홈(18,18a)에 결합된다. 즉, 상기 칼라(10a)가 내부관(4a)의 베이스로 부터 약간 이동되면, 두개의 리브(15,15a)는 제8도에 도시된 바와 같이 상기 홈(18,18a)과 결합되고, 칼라(10a)의 돌기부(9a)는 베어링부(16)에 의해 반경방향 외부로 미소하게 밀려지고, 이 돌기부(9a)의 선단부(19a)는 제7도에 도시된 거리 X보다 다소 큰 X1만큼 내부관(4a)의 외벽으로 부터 이격위치되는 바, 상기 거리 X는 케이스(7a)의 내벽에서 내부관(4a)의 외벽까지의 거리로써 부드러운 회전마찰역할을 하도록 되어 있다.Here, two annular outer races 15 and 15a are formed in the base portion of the inner tube 4a. The outer races 15 and 15a have a triangular cross section, so that the inner tube 4 is the tip of the base portion. It is formed to be inclined upward from the annular bearing portion 16 and the axial direction is formed sequentially, the annular rib 17 is interacted with the outer ring opposite the inner tube (4a) of the inner tube (4a) Axially supported sleeve 6a can be freely rotated, and the ribs 15, 15a of the base portion of the sub-pipe 4a are provided with the collar 10a on the inner tube 4a. It is coupled to internal grooves 18 and 18a formed in the base portion of the collar 10a so as to be fixed in the two positions shown in Figs. 9 and 9 (shown in solid and dashed lines in Fig. 4). That is, when the collar 10a is moved slightly from the base of the inner tube 4a, the two ribs 15, 15a are engaged with the grooves 18, 18a as shown in FIG. The protrusion 9a of 10a is slightly pushed out radially outward by the bearing part 16, and the tip end 19a of this protrusion 9a is inside by X1 which is somewhat larger than the distance X shown in FIG. The distance X is spaced apart from the outer wall of the tube 4a, and the distance X is a distance from the inner wall of the case 7a to the outer wall of the inner tube 4a so as to serve as a smooth rotational friction.

또한, 상기 칼라(10a)가 내부관(4a)상을 따라 가일층 이동되면 상기 리브(15a)만 제9도에서 도시된 바와 같이 홈(18)과 결합되고, 돌기부(9a)의 베이스부는 베어링부(16)로 부터 상대적으로 멀리 떨어져 돌기부(9a)가 상기 거리 X1보다 더 큰 X2만큼 베어링부(16)로 부터 이격위치되는데, 이 거리 X2는 좀더 강한 회전마찰역할을 하는 한편, 상기 돌기부(9a)는 외부 케이스(7a)의 베이스부내벽을 좀더 강하게 누르게 된다.Further, when the collar 10a is further moved along the inner tube 4a, only the rib 15a is engaged with the groove 18 as shown in FIG. 9, and the base portion of the protrusion 9a is bearing part. The projection 9a is relatively far away from 16 and is spaced apart from the bearing portion 16 by an X2 greater than the distance X1, which distance X2 serves as a stronger rotational friction, while the projection 9a. ) Presses the base part inner wall of the outer case 7a more strongly.

따라서, 같은 형상구성으로써 케이스구성품의 조합과정에 내부관(4a)의 베이스부와 칼라(10a)와의 거리를 보다 짧게 혹은 길게 조절하는 간단한 기구적조정을 매개로 슬리이브(6a) 내에서 내부관(4a)의 회전마찰을 바라는 대로 보다 부드럽게 혹은 강하게 조절할 수 있고, 칼라의 돌기부(9a)의 탄성과 마찰강도는 돌기부(9a)의 길이나 단면적으로 크기 또는 베어링부표면의 폭에 의해 결정되는바, 예컨대 돌기부(9a)의 길이가 짧을수록 강하게 되는 한편, 본 발명에 따른 회전마찰 메카니즘은 그 강도를 조절하기 위한 감찰(감擦)이 필요없고, 이와 같은 메카니즘특성을 종래 메카니즘보다 우수한 효과가 있다.Therefore, the inner tube in the sleeve 6a is configured by a simple mechanical adjustment to shorten or lengthen the distance between the base portion of the inner tube 4a and the collar 10a during the combination process of the case components with the same configuration. The rotational friction of (4a) can be adjusted more smoothly or more strongly as desired, and the elasticity and frictional strength of the protrusion 9a of the collar is determined by the size or the width of the bearing part surface in the length or cross section of the protrusion 9a. For example, the shorter the length of the projection 9a, the stronger the rotational friction mechanism according to the present invention does not require supervision for adjusting its strength, and this mechanism characteristic is superior to the conventional mechanism. .
